The Early Church and Peter's Primacy

Letter CXI, from Pope Leo to Emperor Marcian

Synopsis: Leo reports to Marcian that his initial suspicion of Anatolius’s ordination was overcome by Marcian’s testimony and Anatolius’s own profession of faith — but now Anatolius has demoted Aetius the archdeacon, a defender of the Catholic faith, under the guise of promoting him to the presbyterate, assigning him to a cemetery and replacing him with Andrew the Eutychian deacon; Leo asks Marcian to reprove Anatolius, restrain his conduct, and support Julian of Cos as Leo’s own delegated representative.

Leo, bishop, to Marcian Augustus.

Chapter I: Leo’s Initial Suspicion of Anatolius’s Ordination Overcome by Marcian’s Testimony and Anatolius’s Profession of Faith

The whole world recognizes how excellently the glorious zeal of your clemency has in our time restored the integrity of the Christian faith — securing through you, by the Lord, a singular protection of salvation. If any opposition arising from a contrary spirit should contend against the completion of this great work, it must be recalled to the aid of your piety — prepared by divine providence to guard the Catholic truth — since your authority can suppress scandals even at a distance, and far more those that dare to rise under your own eyes. As for Anatolius’s ordination: God is my witness that it was suspect to me, I confess, on account of his consecrators — and I judged the elect to be like those who elected him. Thus, while he remained a stranger to the communion of the Apostolic See, I long abstained from sending him letters of peace when he sought them. But your piety’s testimony was added in support of him — promising that his faith and intention for unity were desirable and pleasing — so I believed his profession to be sincere, and yet I ceaselessly urged proper conduct, diligently admonishing him to shun the persecutors of blessed Flavian’s memory and to truly abhor the followers of Eutychian heresy as enemies of Christ. He seemed to comply: he wrote to me that he had expelled Andrew the deacon, a defender of Eutyches’s heresy; and he wrote to me about the Catholic definitions of the faith established by the synod, as befits a Catholic bishop.

Chapter II: Leo Condemns the Demotion of Aetius and the Promotion of the Eutychian Andrew

With these praiseworthy beginnings, I do not know what cause or occasion arose for him to degrade from the archdeaconry — under the guise of honor — a man of Catholic faith who steadfastly opposes both Nestorian and Eutychian heretics: suddenly transferring all the care of ecclesiastical affairs to Andrew the Eutychianist. So greatly disturbed was he by this that he performed this consecration — given as an injury — on a Saturday, ignorant or forgetful of apostolic tradition: as though the fault of ordination pertained more to a bishop than a presbyter. Finding no fault in faith or conduct, he accomplished the demotion of an innocent man through feigned promotion — adding to the injury by assigning him to a cemetery, a form of exile that is itself a sentence. I commend him to your piety, that he suffer no further harmful schemes — for I learn that the Lord has placed him under your protection.

Chapter III: Leo Urges Marcian to Reprove Anatolius and to Support Julian of Cos as Leo’s Delegate

I add this further plea: deign to reprove the said bishop as necessary — discordant as he is with his own profession and too forgetful of your testimony and favor. Let him cease to oppress Catholics, to crush those who were pleasing to blessed Flavian, and to choose the company of those he had condemned. We cannot extend brotherly charity to him unless he proves himself to execrate the enemies of the Catholic faith and severs all connection with the one he had rightly rejected. For even if Andrew had been greatly purified by satisfaction, after his doubtful return from error he should have been placed in subordination to the Catholic deacons, not elevated above them. Furthermore, I seek from your clemency the goodwill of holding my brother Julian, your venerator, in your affection — since, trusting in the sincerity of his faith, I delegated to him My role against the heretics of this time, requiring his presence with you for the custody of the churches and of peace. Deign to hear his suggestions for the concord of Catholic unity as Mine, pleasing God — who grants you not only a royal crown but a priestly palm.

Dated the sixth day before the Ides of March, in the consulship of Opilio, most illustrious man.

Notes / Historical Commentary

Letter CXI is Leo’s reply to Marcian’s Letter CX, and it shows the same layered relationship between doctrinal authority and pastoral governance visible throughout the post-Chalcedon correspondence. Marcian had asked for Leo’s public confirmation of the Chalcedonian synod; Leo’s reply does not address that request directly but turns immediately to a concrete situation at Constantinople that requires imperial action. The confirmation will come; the crisis at hand is Anatolius’s treatment of Aetius.

The communion-withholding passage in Chapter I is significant and worth reading carefully. Leo states that while Anatolius remained a stranger to the communion of the Apostolic See, he withheld letters of peace from him — the formal instruments by which communion with Rome was expressed and acknowledged. This is the same mechanism visible throughout the corpus: to be in communion with the Apostolic See is to have received its letters of peace; to be excluded is to have been denied them. Anatolius’s acceptance into communion was conditional on his profession of faith and on Marcian’s personal testimony. The mechanism operates here in a personal correspondence rather than in a formal ruling, but the underlying structure is the same as the excommunication of Hilary of Arles in Letter X and the conditions set for reconciliation of Eastern bishops in Letters LXXX and LXXXI.

The Aetius case in Chapter II exposes the gap between Anatolius’s written orthodoxy and his actual conduct. He had written to Leo claiming to have expelled Andrew the Eutychian deacon; he has now restored Andrew to effective control of Constantinople’s ecclesiastical administration while removing the most prominent Chalcedonian defender in the city under the cover of a promotion. The Saturday ordination compounds the offense: Anatolius has violated both the Chalcedonian faith’s defenders and the canonical rule Leo had established for ordination timing in Letter IX. Leo’s comment — “ignorant or forgetful of apostolic tradition” — is a careful formulation that holds both possibilities open while making clear that neither is acceptable.

Chapter III closes with the vicariate formula applied to Julian’s ongoing role: “I delegated to him My role against the heretics of this time.” Julian is not simply a legate who served at Chalcedon; he is the standing vehicle of Leo’s pastoral authority at the imperial court. Leo asks Marcian to hear Julian’s suggestions as Leo’s own — the same logic that governed the legates’ role at the council, now extended to Julian’s continuing presence. The request that Marcian treat Julian’s counsel as Leo’s own is the vicariate in its most personal and direct form: not a council presidency but an ongoing delegation of pastoral voice at the seat of imperial power.

There is a dimension of this letter that the reader should not pass over, and which the formal arguments of the Canon 28 exchange can obscure: Leo is making administrative decisions inside the Church of Constantinople. He is not commenting on a doctrinal question, not responding to an appeal, not ruling on a matter that the parties have voluntarily brought to him. He is specifying who is to hold the archdeaconry, who is to be expelled, and on what conditions Anatolius can remain in the Apostolic See’s communion. These are internal personnel decisions about another church’s governance, issued as conditions by Leo in his own name. A first among equals presides at councils, perhaps, and advises; he does not dictate the administrative arrangements of his peers’ churches and attach communion to compliance. What Leo is doing here is the behavior of a superior toward a subordinate — and Letter CXXXII completes the picture. Anatolius writes to Leo to confirm that he has carried out the directives: Andrew expelled, Aetius restored to his proper place. He frames his report explicitly as compliance with Leo’s instructions. The patriarch of Constantinople, bishop of the imperial capital, the see placed second after Rome by the very council Leo presided over — reports his obedience to Leo and accounts for the internal administration of his own church. The sequence of CXI and CXXXII, read together, is among the most direct demonstrations in the entire corpus that the relationship between the Apostolic See and even the greatest Eastern see was not collegial parity but structured authority.
